WILLIAM SEILER, (JF'KOKOMQITNDIANA, ASSIG-NOB OF ONE-THIRD'TO CHARLESEIAMMOND, OF KOKOMO, INDIAN AUTGMOBILE LOCK.

Application filed July 12,

. To all whom it may concern:

"Be it knownthatL'lVILLIAM'SEILER, a citizen of the United States,residing, at Kokomo, in the county of Howard and State ofIndiana, haveinvented new and useful and is an improvement over my former Pat- 7 entNo. 1,832,? 65, issued March 2, 1920, and

the primefeature of the-present invention is. the provision of anextended neck or outlet for the carbureter so that a lock mecha-' nismmay be introduced in said neck at a point between the carbureter' properand the end of the intake manifold attached to the neck for conveyingthe fuel from the carbureter to the engine.

A further feature of the invention is the provision of a valve soconstructed that it will automaticallv close and cut off the fuel fromthe engine when the lock mechanism is set in one position and be openedand held in open position when the lock mechanism is set in anotherposition.

A further feature of the invention is the provision of means forattaching the extended neck portion of the carburetor direct to theengine.

Other objects and advantages will be hereinafter more fully set forthand pointed out in the accompanying specification.

In the accompanying drawings which are made a part of this application,

Figure 1 is an end elevation of an engine with the improved lockmechanism attached thereto.

Fig. 2 is an enlarged sectional view as seen on line 22, Fig. 1.

Referring to the drawings, 1 indicates an engine of the internalcombustion type and having the usual intake manifold 2 attached theretothrough which the fuel is conveyed from the carbureter 3, which may beof any preferred type and having an extended neck 4 thereon.

The neck 4 is provided with a duct 5 through which the fuel passes fromthe carbureter into the intake manifold 2, the duct preferably turningat right angles at its end farthest from the carbureter so as toconveniently communicate with the opening in the intake manifold.

Extending across the duct 5 and between the carbureter and the dischargeend of the Specificationlof Letters'Patent.

duct is a bridge wall 6, in which is' formed an opening 7 and in thisopening is threaded a seat 8 having a valve opening 9 therethrough.

Cooperating with the valve opening 9 is a valve 10 of the ball typewhich fits into a housing 11, preferably formed integral with the bridgewall 6 and is spaced from the interior wall of the duct to form apassage 12 for the fuel on its course from the carbur'eter to themanifold 2, the wall of the housing having a slot 13 through whichthefuel may pass to the interior of said housing.

The valve 10 is automatically closed and held in closed position bymeans of a spring 14, one end of which bears against the closed end ofthe housing 11 and the other end against the valve 10, and when thevalve is closed the supply of fuel is cut off from the engine. To renderthe engine absolutely inoperative except to those having the right tooperate the automobile to which the engine is attached, the valve is tobe opened and held in open position while the engine is being driven bya suitable lock mechanism, preferably a combination lock 15,comprisingthe usual tumblers 16, which, when set on a certaincombination, permits the forcing of the valve 10 to open position andretains the valve in open position on then scattering the combination ofthe lock. To close the valve again, the tumblers 16 must be properlyarranged to permit raising of 22, when spring 14 will close the valve.

To prevent leakage of the fuel through the parts of the casingsurrounding the lock structure 15, a diaphragm 17 is introduced betweenthe lock and the valve 9 and is secured in position by a sleeve 18 whichis threaded into the casing surrounding the lock and forces thediaphragm against a shoulder 19 to form a perfect seal. This forms acavity 20 between the valve seat and the diaphragm into which the fuelenters after passing through the valve opening 9, the fuel passing fromsaid cavity through a port 21 and into the right-hand side of duct 5.

For convenience of operation, the innermost tumbler 16 has a plunger 22which engages and operates the diaphragm and a similar plunger 23 isattached to the inner face of the diaphragm for engagement with the ballvalve 10. The lock mechanism 15 is also provided with an operating rod24 which preferably extends to any suitable point on the vehicle.

The neck 4: is' extended a distance beyond the end of the duct 5 so thatthe neck may be attached directly to parts of the engine, any suitablemeans being provided for attaching the neck to the engine, such as aflange or cars 25, through which pass bolts 26.

The invention claimed is:

l. The combination with an internal combustion engine, of a carbureter,an elongated horizontally extending neck on said carbureter andextending from the carbueter to the casing for said engine, said neckhaving a fuel duct extending longitudinally therethrough, a valve insaid duct between the carbureter and engine for closing communicationthrough said duct, a lock mechanism 'for opening said valve and meansfor attaching said neck direct to the engine casing.

2. The combination with an internal combustion engine, of a carbureter,an elongated horizontally extending neck integral with said carbureterhaving a fuel duct extending longitudinally thereof the discharge end ofsaid duct being upwardly curved, an intake manifold communicating withthe curved end of said duct for conveying the fuel to the engine, avalve for closing communication through said duct at a point between thecarbureter and the discharge end of the duct, a combination lockmechanism for opening said valve, and means for attaching said neckdirect to the engine casing.

3. The combination with an internal combustion engine, of a carbureter,an elongated horizontally extending neck integral therewith, saidcarbureter having a fuel ductextending longitudinally therethrough, avalve in said duct between the carbureter and the discharge end of theduct, means for auto matically closing said valve, a diaphragm foropening said valve, a lock mechanism for forcing said diaphragm againstsaid valve, and means for attaching said neck direct to the enginecasing.

In testimony whereof I hereto afiix my signature.

WILLIAM SEILER.
